Busuu

Founded in London, England in 2008, Busuu is a language learning platform. It offers instruction in 12 languages and boasts a community of more than 90 million learners around the world.

The platform includes self-paced courses that focus on the basics: reading, writing, speaking, and listening; and combine that with practical speaking or writing practice with native speakers. Its meant to be used for 10 minutes a day. Users can learn on Busuu online or with iOS or Android apps. There is even an offline mode, so you don't need internet access to work on your language.

In 2015, Busuu partnered with McGraw-Hill Education to create a certification program for learners who use the textbook company's courses in class.

Busuu uses a freemium membership model with optional upgrades for access to more features: Premium for casual learners and Premium Plus for more intense learners.
